H init( ) Methods for Oracle Multimedia Object Types

This appendix presents reference information about the init( ) methods for these four Oracle Multimedia object types:

ORDAudio
ORDDoc
ORDImage
ORDVideo

In this appendix, references to ORDxxx objects represent these four Oracle Multimedia object types.

Note:

In Oracle Database 11g Release 2 (11.2), Oracle introduces new constructor functions to construct ORDxxx objects from BLOBs and other sources. The init( ) methods will continue to be available in Oracle Database 11g Release 2. However, Oracle recommends writing new applications to use the new constructor functions. Oracle also recommends migrating existing applications from the init( ) methods to the new constructor functions at your earliest convenience.

See Chapter 3, Chapter 4, Chapter 5, and Chapter 6 for information about the new constructor functions for ORDxxx objects.

This appendix describes these methods:

init( ) for ORDAudio
init( ) for ORDDoc
init( ) for ORDImage
init( ) for ORDVideo
init(srcType,srcLocation,srcName) for ORDAudio
init(srcType,srcLocation,srcName) for ORDDoc
init(srcType,srcLocation,srcName) for ORDImage
init(srcType,srcLocation,srcName) for ORDVideo

init( ) for ORDAudio

Format

init( ) RETURN ORDAudio;

Description

Initializes instances of the ORDAudio object type.

Parameters

None.

Pragmas

None.

Exceptions

Usage Notes

This constructor is a static method that initializes all the ORDAudio attributes to NULL with these exceptions:

source.updateTime is set to SYSDATE
source.local is set to 1 (local)
source.localData is set to empty_blob

Examples

None.

init( ) for ORDDoc

Format

init( ) RETURN ORDDoc;

Description

Initializes instances of the ORDDoc object type.

Parameters

None.

Pragmas

None.

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDDoc attributes to NULL with these exceptions:

source.updateTime is set to SYSDATE
source.local is set to 1 (local)
source.localData is set to empty_blob

Examples

None.

init( ) for ORDImage

Format

init( ) RETURN ORDImage;

Description

Initializes instances of the ORDImage object type.

Parameters

Pragmas

None.

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDImage attributes to NULL with these exceptions:

source.updateTime is set to SYSDATE
source.local is set to 1 (local)
source.localData is set to empty_blob

Examples

None.

init( ) for ORDVideo

Format

init( ) RETURN ORDVideo;

Description

Initializes instances of the ORDVideo object type.

Parameters

None.

Pragmas

None.

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDVideo attributes to NULL with these exceptions:

source.updateTime is set to SYSDATE
source.local is set to 1 (local)
source.localData is set to empty_blob

srcLocation: The source location of the audio data. (See Table 2-2.)
srcName: The source name of the audio data. (See Table 2-3.)

Pragmas

None.

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDAudio attributes to NULL with these exceptions:

source.updateTime is set to SYSDATE
source.local is set to 0
source.localData is set to empty_blob
source.srcType is set to the input value
source.srcLocation is set to the input value
source.srcName is set to the input value

Examples

None.

init(srcType,srcLocation,srcName) for ORDDoc

Format

init(srcType IN VARCHAR2,

srcLocation IN VARCHAR2,

srcName IN VARCHAR2)

RETURN ORDDoc;

Description

Initializes instances of the ORDDoc object type.

Parameters

srcLocation: The source location of the media data. (See Table 2-2.)
srcName: The source name of the media data. (See Table 2-3.)

Pragmas

None.

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDDoc attributes to NULL with these exceptions:

source.updateTime is set to SYSDATE
source.local is set to 0
source.localData is set to empty_blob
source.srcType is set to the input value
source.srcLocation is set to the input value
source.srcName is set to the input value

Examples

None.

init(srcType,srcLocation,srcName) for ORDImage

Format

init(srcType IN VARCHAR2,
